In Illinois, 60 percent of inmates were foreign-born or second-generation immigrants—Irish and German.
In California, 45 percent of prisoners were foreign-born—predominantly of Chinese, Mexican, Irish, and German descent
Throughout the post-Civil War years, the rate of imprisonment for foreign-born Americans was twice that of native-born ones; black Americans were incarcerated, North and South, at three times the rate of white Americans
